Application filed May 19, 1909. Serial N 0. 496,875.

To all whom it may concern:

Be it known that I, DUDLEY GARsr, a citizen of the United States of America residing at Waterloo, in the county of .Bl ackhawk and State of Iowa, have invented certain new and useful Improvements in Manure- Spreaders, of which'the following is a specification, reference being hadtherein to the accompanying drawings. 1

This invention relates to manure spreaders and more particularly to an arrangement of parts adapted to insure even distribution and to check any tendency ofthe operating parts to race or. jump.

The invention consists in the matters hereinafter set forth and more particularly pointed out in the appended claims.

In the drawings, Figure .1 is' a view inside elevation, of a spreader embodying. features of the invention, with parts removed. Fig. 2 is a plan view of the spreader, with parts of the operating mechanism omitted.

Referring to the drawings, the running gear of a wagon, with front bearing wheels 1 and rear traction bearing Wheels 2, carries a box that is of standard construction save that it tapers from front to rear. A beater 4 of any preferred design, is journaled across. the narrow rear discharge end so as to pickup the box contents and throw it out, as it is advanced against it by any suitable form of endless conveyer 6 whose upper loaded limb traverses the box bottom from front to back. The beater and conveyer are drawn from the rear wheels form of transmission gearing, as, for example, the sprocket-and-chain connections i-ndicated'at 7.

The chief feature'of the invention is the arrangement of the uniformly converging side-boards 8 whereby apositive feed is necessary to move thebox contents against the beater, and whereby the friction of the load against the sides is sufficient toprevent the'conveyer jumping or slacking back, if a wheel drops into a hole,'or if other circumstances permit it. I Other retarding devices have been used in the shape of cross-bars or other baflles to friction'ally impede the contents of the box as it is drawn toward the beater and hold-it against sudden movements forward or back, but their action is struction may be made without 2 by any preferred either irregular or else it imposes too heavy a load on the driving gear. The convergent sides which are smooth on the inside, press upon the load throughout its length and thus keep it in substantially the same degree of compactness, not allowing any portion to break away, andthus presenting a homogeneous mass to the actionof the beater, so that the distribution by the latter is even and uniform.

Obviously, changes in the details of condeparting from the spirit of the invention, and I do not care to limit myself to any particular form or arrangement of parts.

WVhat I claim as my invention is z- 1. A manure spreader comprising a box tapering from the closed end to the discharge end, means for forcing the contents of the box uniformly from the closed to the discharge end, and distributing it therefrom, and running 'ear supporting the box and operating the fbrcing andf distributing means. i

2. A manure spreader comprising a box havin 'a closed end and a discharge end toward which the box tapers laterally throughout its length, traction bearing wheels for the box, and a conveyer driven thereby adapted to force the box contents from the closed to the discharge end.

3. A manure spreader comprising traction bearing wheels, a 'box horizontally disposed thereon and provided with sides conver ing from the closed end to the discharge en an endless conveyer. traversin the bottom of the box from the closed to t e discharge'end, and operating connections between the conveyer and the traction wheels.

4. A manure spreader comprising traction bearing Wheels, a. box maintained thereon tapering laterally from its closed end to its discharge end, distributing means at the discharge end, and a conveyer adapted to force the cont nts of the box toward the distributing means and driven by the traction wheels. In testimony whereof I aflix my signature in presence of two witnesses.
